Subject: [PATCH] test: avoid hanging forever waiting for udev if not a booted
 system

test_sd_device_enumerator_filter_subsystem hangs forever in OBS builds,
as it waits for the udev queue to be drained. But this is not a booted
system, with systemd and udev, so nothing will do that.
Skip the test in that case.
